When CI Passes but App Review Rejects Your Screenshots — Field Notes on Measuring the Freshness of Your Validation Rules
Store asset validation can pass in CI and still get rejected in review, because the rules themselves go stale. Move store specs into a freshness-dated contract file, then add locale overflow checks and perceptual diffs.
Hand Over Generation and Shipping, but Never the Signing Key — Designing Key Custody and Handover for an AI-Driven Pipeline
Even in an era where AI Studio and Antigravity take over everything from generation to internal-test shipping, the app signing key is in a class of its own. Lose it, and that app can never be updated again. As a solo developer who has run several apps for years, here is how I design key custody — separating the upload key from the app signing key, storing it, and planning the handover for the worst case.
When an AI Studio App Won't Install on My Phone Because the Signatures Don't Match
You generate a Kotlin/Compose app in AI Studio, push it to a real device over USB, and the install dies with INSTALL_FAILED_UPDATE_INCOMPATIBLE. Here is why a debug-signed build can't overwrite your Play release, and how to test it without losing your production app.
The Day Generation, Device, and Internal-Test Shipping Became One Step — What I Refused to Hand Over
AI Studio now turns a text prompt into a Kotlin/Compose app and carries it through the emulator, a real device, and Google Play's internal test track from one screen. Behind that convenience sits a question: how much of the moment of shipping do you hand to the machine, and what do you keep in your own hands? Here is where I draw the line as a solo developer running several apps, and the implementation that holds that boundary.
Feeding Store Review Guidelines as a PDF to the Agent to Build a Per-App Pre-Release Checklist
